I BARB-WIRE MACHINE.

SPEGIFIGATION forming part of Letters Patent No. 707,315, dated August 19, 1902.

Application filed November 18, 1901. Serial No. 82,629. (No model.)

To all whom 'it may concern:

Be it known that we,HENRY GAUERMAN and DAVID PRYDE, citizens of the United States, residing at Braddock, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and usefulImprovements in Barb-Wire Machines, of which the following is a specification.

In the accompanying drawings, which make part of this specification, Figure I is aside elevation of a barb-wire machine; Fig. II, a plan View of the same; Fig. III, anenlarged plan View, partly broken away, showing the barbing and cutting mechanism; Fig. IV, a plan View showing the barbing-spindle, the strand-wires and the strand-wire guide being shown rotated ninety degrees from their normal position; Fig. V, a side elevation of the same, showing parts of the rotating and reciprocating mechanism in detail; Fig. VI, a detail view showing the front of the double cam; Fig. VII, a detail section on line VII VII of Fig. I; Fig. VIII, a detail side view of the mechanism for intermittently drawing the wire forward after each barbing operation; Figs. IX, X, and XI, modifications of Fig. VIII; Fig. XII, a detail of the barb-wire feed, and Fig. XIII a vertical section taken through the fixed cutters 29 immediately to the right of the numerals 28 28 on Fig. III and through the shaft 4: immediately to the right of cam 24 in Figs. I and V. This view is for the purpose of showing the details .of the cams 24 and 25 and of the knives, all other parts of the machine not being shown.

Heretofore in the construction of barb-wire machines the mechanism for drawing the wire forward and themechanism for reciprocating the barbing-spindle have been so designed that it has been a source of continual annoyance and expense to keep the machines in repair. Besides, the maximum speed has been limited by reason of the use of inferior mechanical movements, more particularly the reciprocating devices and the complicated arrangements used in drawing the barb-wire forward.

It has been our aim to simplify the construction of barb-wire machines in -two of their most essential features-namely, the means for reciprocating the spindle and the mechanism for drawing the wire from the barbing position. By so doing we are onabled to increase the speed of our machine, whereby its output is over twenty-five per cent. greater than that of any machines known to us. I

We have somewhat modified the other parts of the machine, sothat they are in conformity with the general simple construction of the parts on which we desire to base our claims.

The objects of our invention, generally stated, are, first, to. simplify the mechanism for drawing the wire forward after barbing; second, to provide a more substantial construction and operative means for reciprocating the coiling-spindle; third, to cheapen the construction;;fourth,"to dispense with all springs used in connection with the reciprocating head, and, fifth, to improve and increase the output.

In the drawings, 1 designates a hollow shaft rotating in stationary supports or journalboxes 1 and carrying at one end a cap 7, in which are set the coiling-pins 8, and at the other end a pair of collars 9, forming between them a groove 10, in which lie the upper members 10 of. the post 11, secured to the horizontally-movable reciprocator 12. The reciprocator slides between guides 13. The lower member of the post 11 extends below the table on which the several parts of the machine are mounted and carries an antifriction-roller 15. Beneath the table is a shaft 4, on which are secured the spur-wheels 3 and 3, the disks 24 and 25, and the cam 14:. The wheel 3 gears with pinion 2 on shaft 1, and cam 14 is provided with a peripheral cam-groove 14, which receives the roller 15.

Rigidly supported on bracket 6 isahollow.

tube 5, which lies in the hollow of the shaft 1 and has at its front end the strand-wire guide 5. A main shaft 16 extends along the side of the machine below the table and carries at one end the spur-wheel 53 and at the other end the wrist-pin 17. On the shaft 16 intermediate of the pin 17 and gear 53 are a worm 30 and a spur-wheel 16, the latter meshing with the pinion 3' on the shaft 4. The wrist-pin 17 is connected by link 18 to the oscillating carrier 18 of the pawl 19, which engages ratchet-wheel 20 on the shaft 21 at the side of and above the shaft 16, as shown on Fig. XII. Shaft 21 is connected to fixed cutters 29 like shears.

a cross-shaft 23 by bevel-gears 21 and carries the lower barb-wire-feed roll 22, which has a grooved periphery, and a spur-wheel 21 which meshes with spur-wheel 21 on the shaft 21 carrying the upper flat-faced barb-wirefeed roll 22. The crossshaft 23 extends across to the opposite side of the machine, where it drives a second set of barb-wire-feeding mechanism similarin construction to the set just above described.

26 26 represent two knife-carrying levers mounted on pins 26 in supports 26 and having their lower ends 26 lying partially between the disks 24 and 25, provided, respectively, with cams 24 and 25, lying diametrically opposite. The ends 26 of the levers are provided with lateral pins carrying rollers 26, which are simultaneously engaged by the cams 24 and 25. Seated in the upper partof the levers 26 above their pivots are the hollow cutters 28, held in place by cap-plates 27. These cutters each have a beveled face which cooperates with the beveled face of the The barb-wires b pass through the hollow cutters 28,as shown in Fig. XIII, and lie on top of the fixed cutters just back of their points, so that when the cutters 28 are rocked downwardly by the cams 24 and 25 the wire will be sheared off between the top of the fixed cutters and the top wall of the hollows in the pivoted cutters.

The worm 3O meshes with the worm-Wheel 31, carried by the sleeve 35, which has rigidly secured thereto the spur-wheel 34. Below the collar is a stub-shaft 39, on which rotates the pinion 38, carrying rigidly on its hub extension a spur-gear 40. The pinion 38 is held on the shaft 39 by the nut 42 and washer 44. The sleeve 35 carries the shaft 32, on which rot-ate the pinion 36 and the sprocketwheel 37, secured rigidly together, the latter pulling the barbed wire after each barbing operation. The worm 30 has its threads staggered or offset, as shown in Figs. 1 and VIII, at one portion, the remaining part of the threads lying in planes at a right angle to the shaft 16. The staggered worm rotates continuously, but only causes a movement of the worm-wheel 31 and sprocket-wheel 37 when the staggered or offset portion engages the worm-wheel.

It will be noted that pinions 36 and 38 are smaller than spur-wheels 34 and 40. Hence by substituting for pinions 38 and wheel 40 a pinion and wheel of relatively different diameters the speed of sprocket-wheel 37 will be changed to suit whatever speed might be required.

Figs. IX, X, and XI show the worm reduced to a single thread or a part thereof; but we regard all these forms as coming within the terms worm and offset or staggered thread and the like used in the claims.

Pivotally supported on the fioor beneath the table is a standard 45, carrying at its top the take-up idler sprocket-wheel 44, over which the barbed wire passes in its travel from feed-wheel 37 to the reel or coiling-drum 48, mounted in the flier or twister frame 50.

47 is a guide-wheel traveling on the reversely-threaded screw to distribute the wire on the drum.

The reel 48 is continuously rotated from the fixed pulley 49 by means of intermediate gearing driving the shaft 51, the same forming no part of the present application. The flier 50 is also driven by pulley 49 and has at its inner end the neck 54, on which is mounted the gear-wheel 56. On stub-shaft 57 is a pinion 58, meshing into gearwheel 59 on main shaft 16, wheels 56 and 58 being rigidly united.

The operation of the machine is as follows: The strands of wire Ct are passed through the hollow tube 5 and through the wire-guide 5 in the forward end of said tube. The barbwires b b are then passed between the feeding-rolls at the sides of the machine, said Wires passing through the movable cutters 28, over the stationary cutters 29, and between the strand-wires a, the ends of the barb-Wire being fed forward approximately the desired distance to twist around the strand-wires. At that instant the rotating coiling-head, with its two projecting pins 8 8, moves suddenly forward, so that one of its pins engages one of the ends 60 and the other the second end 60 of the barb-wires, bending them respectively up and down, and as the rotation continues these ends are wrapped around the strand wires the desired degree. As the wrapping takes place the coiling spindle and head gradually recede from the forward position to compensate for the helical path of the barbs until the barb is completed, whereupon the coiling-spindle moves suddenly, drawing its pins out of reach of the barb. Preferably the coiling spindle revolves four times to each revolution of the shafts 4 and 16-that is, four times to every barb applied to line-wires; but only one and one-quarter turns thereof are of service in twisting the barbs, it being merely a matter of keeping it going at a uniform rate rather than to stop and reverse it. At the instant the barb is completed the cutters 28 act suddenly to sever the completed barb cfrom the incoming wires, following which the strandwires (1 are fed forward the distance it is required to have the barbs 0 attached thereto. The barb-wire feed is so timed that as soon as the line-wires have advanced about onethird of their entire movement said barbwire rolls 22 and 22 begin to feed their wires forward, preferably the time allowed for feeding being one-half a revolution of the main shaft 16.

In Fig. IX we have shown the power transmitted from the staggered thread to the shaft d (which corresponds to shaft 32 in Fig. VIII) by means of gears c and f. These gears can be removed and others substituted when desired in order to vary the length of wire fed at each operation.

In the subjoined claims we do not, of course, limit ourselves to the particular details of mechanism shown in the drawings herewith and described in the accompanying specification, as the same can be modified indefinitely by any skilled constructor now that we have described the principle on which the reciprocating and strand-wire-feed mechanism should work. Therefore believing that We are the pioneers in these particular principles when applied to barb-wire machines we claim the same broadly.
